Block chain-based data management method and apparatus, and storage medium

Abstract

The invention provides a block chain-based data management method and device and a storage medium. The method is applied to a management server and comprises the steps that a registration request message sent by a management node is received, the registration request message comprises related information of the management node, and the related information comprises at least one of the following information: identification information of the management node, a public key of the management node and attribution operation main body information; wherein the management node comprises at least one ofthe following servers: an authorization server, a card provider server, an operator server and a terminal manufacturer server; when the related information of the management node passes the verification, identification information and signature information are distributed to the management node; first signature data sent by the management node is received, wherein the first signature data is datagenerated by the management node according to the identification information and the signature information; and the first signature data is stored in the block chain. According to the data managementmethod and device and the storage medium provided by the invention, the requirement that each management node rapidly shares information can be met.

Description

technical field [0001] The present invention relates to the field of data management, in particular to a blockchain-based data management method, device and storage medium. Background technique [0002] With the rapid development of smart technology and the Internet of Things, EUICC (Embedded Universal Integrated Circuit Card) is an embedded SIM card, which is an improvement on the basis of the traditional SIM card. EUICC is directly embedded on the circuit board. , there is no need to set up an independent card slot, so that, on the one hand, it can save space, enhance the waterproof, dustproof and shock resistance of smart devices, and adapt to the requirements of complex environments such as underwater, soil and desert of the Internet of Things; on the other hand, no Manually participate in the insertion and removal of the SIM card, and EUICC can also download user data on demand based on the Internet, and can perform remote control, which makes the use of smart devices m...

Problems solved by technology

[0005] In the existing technology, management entities such as card vendors, operators, certificate authorization centers, and terminal manufacturers are only responsible for their internal management, and there is no information or data interaction between management entities. If one of the management entities contains information or If the data is updated, other management entities will not be able to obtain updated information or data in a timely manner, and the information between management entities cannot be shared
